Years ago I reloaded thousands of rounds of 7/8 oz. loads when the International Trap (Bunker) rules specified that charge weight as the upper-bound limit on shot volume. My best recipe was Win AA case; W 209 primer, 18.7 grains of 700X under the Federal 7/8 oz. wad (I think it was the SO 3) and 7/8 oz. of high-antimony ("magnum") shot. It is a great load; high velocity with realtively low recoil and I think the pressure is somewhere up in the 9800 psi. range. Probably way too stout for Damascus guns but a real target crusher in a fluid steel gun. KBM
